Not All Surfactants are Created Equal
Surfactant structure, actual surfactant load and humectant content are all important variables that work
together to influence the performance characteristics of a nonionic surfactant. However, most surfactant
labels do not provide precise information relative to the true content of the formulation.

In 2001, the Council of Producers & Distributors of
Agrotechnology (CPDA) launched a voluntary
Adjuvant Certification Program to encourage
good product stewardship in the manufacture
and labeling of agricultural adjuvants. Under
this program, adjuvant manufacturers provide
specific formulation information to a panel of
industry experts for review. Product label claims
are scrutinized for accuracy and conformation to
accepted industry definitions and standards before
certification is granted.

For nonionic surfactants, the top three formulation
components must be listed on the label and the
actual surfactant content must be separately
stated, giving applicators a clearer picture of the
adjuvant’s formulation and performance potential.

VERTEX PERFORMANCE WITH RIMSULFURON
100
Vertex is formulated for applicators that expect
to deliver the best performance possible, and
want the associated assurance of complying with
pesticide labels that state a preference for a CPDAcertified surfactant. With a higher true surfactant
load than most surfactants on the market, Vertex
maximizes pesticide performance by improving
spray solution wetting, coverage and penetration
of target leaf surfaces.

Efficacy Data is Still Important
CPDA Certification is not a substitute for efficacy
data, but it narrows down the field of choices
to those most likely to deliver higher levels of
performance under a wider range of growing
conditions. Remember to ask suppliers for
performance data before making your choice.
